'ro ALL wHoM rr MAY coNcERN:

Be it known that I, HENRY HASSENPFLUG, of Huntington, in the county of Huntington, and State of Penny Sylvania, have invented an improved Saw/ing Machine; and I do hereby Adeclare that the following, taken in'T connection with the drawings which accompany' and form part of this specification, is a description of my invention sucieint to enable those skilled in tlie art to practise it.

The drawings represent a mechanism embodying my invention.

` a denotes a'strong frame, onel end of which is provided with one or more wheels, b, and Athe other -with handles, c, or shafts, so that while the carriage may be propelled l like a barrow, it willv stand firmly in position when at rest by means of the posts, d d. The posts or standards, d', have ways or guides, inwhich slides a vertical reciprocating `saw frame, e, to lthecrossbarsd", of which slotted arms g are clamped ajig or long saw, It, being strained between the two arms,` as seen .in iig. 2. The saw works through a horizontal sliding bed" or carriage, z', provided with a transverse rest, lef-against which the log is supported, if to be out crosswise, or a longitudinal rest or guide, Z, against which it is 'held'if to be slit lengthwise. Beneath this carriage is \a loose shaft carrying a grooved pulley, m, over Which-"acord o'r chain, n, rnns, one end of this cord being attached to the carriage, and the otherrendlhaving a weight suspended from it, the feedof the log to the saw being produced by the action of` this weight, as will be readily understood. The carriage slides upon ways on the frame, a, and is kept from vertical movement by plates, o, fastened tothe frame and projecting into grooves,p, in the opposite `-sides of the carriage) A sliding dog, p', serves to clamp the log to the surface of the carriage and against the rest piece, c, as willbe readilyunderstood. Motion is communicated to the saw frame from the drivingshaft, g, by a gear, r, and pinion, s, one end of the saw frame being jointed to the pinion by a connecting rod, t, and

the other end similarly connected to a crank wheel upon the opposite end ofthe pinion shaft. The drivingy shaft is provided at each end with-a hand-crank wheehu, so that the saw frame' may be driven by hand power at each side of the machine.` The shaft also carries a crank, c, to which a trcadle, w, is connected, said treadle lever extending under the frame, a, so that the operator who places the wood in position may also aid in driving the saw. The driving shaft also carries a circular saw, a', which, by application of .the bed piece, y, maybe employed for sawing light stui, either while the other- 'saw is operating or when said long-saw is at rest. To disconnect the saw frame, e, from the driving shaft, the pinion shaft is made capable of lsliding in its bearings suiciently to carry the pinion into or out of connection with the driving gear, r, a swinging block, z, serving to keep the pinion and gear in connection when the saw frame isto be driven, and a similar 'block upon the opposite side ofthe frame serving to keep the pinion and gearA out of connection when the circular saw alone is to be driven. The two slotted arms between which the saw is strained are cach provided with screws and nuts, by means of.which the saw may be set at any required distance in frontof the saw frame, in accordance with the general size of the stuff to be sawed or the direction of cut. Friction rolls, a2, are mounted on and beneath the saw frame to run in contact with the opposite sides of `the groove or ways in which the saw frame reciprocates, to prevent contact and friction of the frame with the -ways. A stop pin, b2, serves to hold the carriage, z', at restwhen necessary, as will be readily understood. It will be obvious that Ythe mechanism may be driven by steam or horse power, but the machine is intended principally for a portable wood-sawing apparatus, to be wheeled about and operated by hand. l

I claim the arrangement of 'the slotted arms, with respect `to the saw frame, in Such manner that the saw may be set at any required distance'in advance of 'the frame, substantially as set forth.
